This project aims to characterize the spatial and temporal distribution of the deformation in the region of the Afar depression. The aim is to better understand large-scale tectonics (localization of divergent borders, kinematics of the triple point), but also the dynamics of volcanic, seismic and aseismic events, and the mechanics of active faults. The issue of gravity hazard will also be addressed.

Caucasus
|
The aim of the project is to gain a better understanding of the distribution of deformation associated with convergence between Arabia and Eurasia in the Caucasus region, where various reverse and strike-slip faults with high seismic hazard co-exist. It should enable to propose a regional kinematic and seismo-tectonic model, and quantify vertical movements in particular. Complementary objectives include monitoring mud volcanoes in Azerbaijan, which erupt frequently, and anthropogenic deformation.

Central Chile
|
The project aims to quantify the deformations associated with the Andean subduction in central Chile, with the main objectives to (1) constrain the kinematics and interseismic coupling of the subduction interface and crustal faults, at the front and inside the Andes mountain range, (2) analyze co- and post-seismic deformations during different seismic crises and slow slip episodes, (3) understand the link between the seismic cycle and relief building, (4) monitor the behavior of volcanoes in the Andean arc. Another objective is to characterize erosion episodes during extreme climatic events in the Atacama Desert.

Himalaya and western Tibet
|
This project complements the East Tibet project of the 1st FLATSIM call, with the aim of quantifying the tectonic deformations associated with the India-Asia convergence, from the Himalayan front and across the Tibetan plateau, characterizing lithospheric rheology and hydrological, landslides and cryosphere-related processes. Possible links between the seismic cycle, external forcings and relief construction will be explored. More methodological aspects, such as the quasi-absolute referencing of InSAR measurements, will also be addressed.

Levant

The main objective of the project is to analyze the coupling distribution (i.e. segmentation into locked zones or aseismic slip zones) along the active fault system of the Levant, in relation to historical earthquake sequences and the physical properties of the faults, with a view to improving the estimation of seismic hazard. The project also includes the study of hydrological processes and their forcings (anthropogenic in particular, related to water resource management), or gravitational processes (landslides and factors controlling their onset and velocity).

Maghreb

The main aim of this project is to quantify tectonic deformation across the Maghreb, in the African/Eurasian convergence zone. In particular, it aims to estimate the spatial distribution and temporal evolution of interseismic deformation or deformation associated with recent earthquakes on active faults, from the coast to the Saharan platform. Secondary themes (landslides, coastal subsidence, dune movement in the Sahara, anthropogenic deformation associated with major structures, natural resource extraction, agriculture, etc.) will also be addressed.

Makran
|
The project aims to analyze strain partitioning along the Makran active margin, a convergence zone between Arabia and Eurasia. This region is characterized by major thrust fault systems and laterally variable seismic behavior (large earthquakes in the east, more moderate seismicity in the west). The mode of strain accumulation on active tectonic structures will be analyzed together with the lithospheric structure and geology, in order to better constrain the seismic hazard and geodynamic history of the region.

This project focuses on the southern part of the East African Rift in the Mozambique region. This incipient plate boundary zone, with a low rate of extension, has experienced several Mw> 5 earthquakes since the 20th century. The aim of the project is to extract the tectonic signal from the InSAR time series in order to better characterize the active structures (normal faults) and their kinematics, which are still poorly constrained.

| France |
FLATSIM products have also been calculated for the whole of mainland France in the SNO ISDeform. After post-processing at ISTerre (UGA) and validation by ISDeform (during 2024), these products will also be made available via a dedicated collection in the ForM@Ter catalog. The project focuses on tectonic, hydrological, landslide and rock glacier applications. It can also be used to monitor the compaction of sedimentary basins, deformations associated with the exploitation of the subsoil (storage, mining, hydrothermalism) and certain infrastructures (embankments, etc.) |
